Torsades de pointes is a ventricular tachycardia, meaning that it is a fast heartbeat with the electrical activity from the ventricles. The ventricles are the two lower chambers of the heart that. Torsades de pointes can have life-threatening complications, so immediate treatment is vital. Treatment will vary, depending on the individual's symptoms and the cause of the abnormal heart rhythm Torsade de pointes is an uncommon and distinctive form of polymorphic ventricular tachycardia (VT) characterized by a gradual change in the amplitude and twisting of the QRS complexes around the isoelectric line (see the image below). Torsade de pointes, often referred to as torsade, is associated with a prolonged QT interval, which may be co.. Torsade de Pointes (TdP) is a form of polymorphic ventricular tachycardia associated with a long QT interval on the resting ECG. Torsade de Pointes is typically initiated by a short-long-short interval. A ventricle extrasystole (first beat: short) is followed by a compensatory pause
Torsades de Pointes Torsades is defined as the combination of polymorphic ventricular tachycardia plus a prolonged QT-interval. Torsades can be caused by either congenital long-QT syndrome or acquired long-QT syndrome (due to electrolyte abnormalities and/or medications) Torsades de Pointes: Frequent PVCs with 'R on T' phenomenon trigger a run of polymorphic VT which subsequently begins to degenerate to VF. QT is difficult to see because of artefact but appears slightly prolonged (QTc ~480ms), making this likely to be TdP A run of torsade de pointes in a 70-year-old man who developed QT prolongation (QTc = 0.61 sec) secondary to quinidine therapy. The bottom strip shows resolution with overdrive ventricular pacing Torsades de pointes eller torsade de pointes ( TdP eller ganske enkelt torsade (r)) ( fransk: [tɔʁsad də pwɛ̃t], oversatt som vri på toppene), er en spesifikk type unormal hjerterytme som kan føre til plutselig hjertedød.Det er en polymorf ventrikkeltakykardi som utviser distinkte egenskaper på elektrokardiogrammet (EKG). Det ble beskrevet av François Dessertenne i 1966 Torsades de pointes is usually not sustained and terminates spontaneously but frequently recurs unless the underlying cause is corrected. Torsades de pointes may degenerate into sustained ventricular tachycardia or ventricular fibrillation

Torsades de Pointes is associated with QTc prolongation, which is the heart rate adjusted lengthening of the QT interval Torsades de pointes is a specific form of polymorphic ventricular tachycardia in patients with a long QT interval. It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the electrocardiogram (ECG) baseline. This arrhythmia may cease spontaneously or degenerate into ventricular fibrillation . Recently, an increasing number of non-cardiac drugs have also been reported to have the same effects. These drugs share the same ability to block the rapid component of the delayed rectifier potassium channel (IKr), resulting in inhomogeneous lengthening of action potential, T wave.

Author information: (1)Department of Medicine, School of Medicine,University of North Dakota, Fargo 58102-3677, USA. firstname.lastname@example.org OBJECTIVE: To present a case of fluconazole-associated torsade de pointes (TDP) and discuss fluconazole's role in causing TDP However, a recent study demonstrated that the use of this drug was associated with decreased in-hospital survival and an increased frequency of ventricular arrhythmias when used for treatment of COVID-19. 3 We present a case of severe QT interval prolongation leading to 'Torsade de Pointes' (TdP) in a COVID-19 patient in the intensive care unit (ICU) Torsade de pointes has been attributed to fluconazole.. A 33-year-old woman with systemic lupus erythematosus was given intravenous fluconazole 200 mg/day for C. albicans pneumonia (36 A).She developed prolongation of the QT c interval and torsade de pointes. She had also been given domperidone, and both that and the fluconazole were withdrawn, the domperidone being suspected as the causative.
'Spontaneous torsade de pointes was suppressed, and the vulnerable window during which TdP-induction occurs was also reduced in both models.' 'Certain psychotropic medications and somatic medications can increase the risk of lethal torsade de pointes through a mechanism of blocking cardiac conduction channels. Torsades de pointes is an uncommon cause of cardiac arrest. It is generally quite treatable, but if treated inadequately it will often recur (in some cases leading to repeated salvos of ventricular tachycardia, one form an electrical storm) Torsades de Pointes on the electrocardiogram. The diagnosis of torsades de pointes is made based on the characteristic EKG findings. It is important to record a 12-lead EKG for a correct diagnosis, because in some isolated lead can be observed as a monomorphic VT, while in others it will have the typical torsades de pointes pattern torsades de pointes: [ tor-sahd´ duh pwahnt ] an atypical rapid ventricular tachycardia with periodic waxing and waning of amplitude of the QRS complexes on the electrocardiogram. It is usually drug related and may be either self-limiting or progressing to ventricular fibrillation

Characteristic Pattern of TdP. The term torsade de pointes was coined by Dessertenne in 1966 as a polymorphic ventricular tachycardia characterized by a pattern of twisting points. 1 Several ECG features are characteristic of TdP and are illustrated in Figure 1.First, a change in the amplitude and morphology (twisting) of the QRS complexes around the isoelectric line is a typical feature of. RESULTS: All drugs that cause torsade de pointes prolong the QTc interval and bind to the potassium rectifier channel, but the relationships are not precise. Prediction of torsade de pointes and sudden death can be improved by examining dose dependency, the percent of QTc intervals higher than 500 msec, and the risk of drug-drug interactions Torsades de pointes or torsade de pointes (TdP) (French: [tɔʁsad də pwɑ̃t], translated as twisting of peaks) is a specific type of abnormal heart rhythm that can lead to sudden cardiac death.It is a polymorphic ventricular tachycardia that exhibits distinct characteristics on the electrocardiogram (ECG). It was described by French physician François Dessertenne in 1966 torsades de pointes is thought to result from prolonged repolarization and early afterdepolarizations. when early afterdepolarizations reach the threshold potential and depolarize the cell membrane, triggered activity occurs, resulting in additional action potential Torsades de-pointes 1. PHARMACOTHERAPYOF TORSADEPOINTES 2. Torsade de pointes or torsades is a Frenchterm that literally means twisting of thepoints is a ventricular tachycardia associatedwith a long QT time on the resting ECG. During Torsade de pointes the ventriclesdepolarize in a circular fashion resulting inQRS complexes with a continuously turningheart axis around the baseline (hence.
Torsades De Pointes is a French term that literally means the twisting of the points seen in a rare type of ventricular tachycardia, in which the ventricular tachycardia creates a unique illusion of twisting itself around the iso-electric line (ECG baseline) Figure 1: Torsade de pointes in a long QT syndrome type 2 patient. Although QT prolongation and TdP can be acquired due to use of certain drugs and a variety of pathophysiological conditions such as electrolyte disturbances, ventricular hypertrophy, and Takotsubo cardiomyopathy, the term LQTS is normally used to refer to the congenital forms of QT prolongation Vos MA, de Groot SH, Verduyn SC, et al. Enhanced susceptibility for acquired torsade de pointes arrhythmias in the dog with chronic complete AV block is related to cardiac hypertrophy and electrical remodeling. Circulation 1998;98:1125-35. PubMe Torsade de pointes is usually self-limited but may degenerate into VF and cause sudden cardiac death. A variety of medications have been implicated in drug-induced LQTS. QT prolongation and TdP are the most common reasons pharmaceuticals are restricted or removed from the US market. 3 We review mechanisms, predispositions, culprit agents, and management of this potentially fatal phenomenon 1.
